BASKET-SPLENT MACHENE.

SPECIFICATION forming part of Letters Patent No, 304,021, dated August26, 1884.

Application filed June 11, 1884. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL OAKMAN, of Melrose, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Basket-Splint Machines, of which the following isa specification.

The object of my invention is to so construct the cutter-head andbed-plate that the knives of the cutter-head will mold a flat strip ofwood into a series of plano-convex splints and at the same operationseparate them, so that when they leave the delivery-rolls of the machinethey are finished and ready for use. I attain these objects by themechanism illustrated in the accompanying drawings, in which-- Figure 1is a vertical section of my machine. Fig. 2 is a plan view of the same,and Fig. 3 is a detail.

A, Fig. 1, represents the base, to which the frame A of the machine isattached.

0, Figs. 1 and 2, is a pulley attached to the shaft B. This pulleyoperates the feeding-in and withdrawing rolls of the machine. Theintermediate mechanism between the shaft B and the actuating-rollsconsists of the pinion B, Fig. 1, which operates the large spur-gearwheel B, attached to the low-'crfeed-roll, 13*. Upon the shaft of thelower feed-roll, B, is attached a spur-gear wheel, B, which, operatingthrough the pinion B, moves the spurgear 13 said spurgear B beingattached to the shalt of the lower drag-roll, B, and as the gear-wheelsB" and B are of the same diameter the lower feed-roll, B, and the lowerdrag-roll B will move with the same velocity.

N and N, Fig. 1, represent, respectively, the upper feed-roll and theupper drag-roll. The upper feed-roll, N, and the lower feedroll, B", ofFig. 1, are geared together at E, Fig. 2. The upper drag-roll, N, andthe lower drag1'oll, B Fig. l, are geared together at D, Fig. 2, so thatboth feed and drag rolls move with a uniform velocity.

F, Fig. 1, is a cutter-shaft, to which cut tors 13 are attached. Thiscuttershaft is driven by the pulley]? at a velocity very much exceedingthat of the feeding motion, so that,

although the cutters act in the same direction 5c that the riven wood 1?moves, they will mold it into shape. The cutters 13 have theircutting-edges shaped as shown in Fig. 3. The points n extend so fardownward as to come within the nearest contact of the bed H that can bepractically maintained without actual contact.

In use I place this piece I? of riven wood between the feed-rolls N andB of Fig. 1, the said rolls forwarding the wood into the field of actionof the cutters F and thence through the drag-rolls N and B As theprojecting points a n of the cutters F come infinitesi mally near thebedplate H, the wood P is separated into plane-convex strips, as indi- 6cated at P, Fig. 2, ready for use for wicker work. i

I am aware that knives having corrugated cutting-edges have been used inwood-working machines; but ganizcd machine has been made or used for thepurpose of molding and severing from thin strips of basket-wood splintscompleted and ready for use for wicker-work. All other machines fordividing wood into splints or fila- 7 mcnts take the same off from thickpieces of wood by knives moving in a plane and not re volving, and thefilaments thus severed are not with the grain of the wood, but are moreor less cross-grained. My machine secures 8 filaments with the grain inline-that is, the filament made by my machine is as strong as it ispossible to make woodfilaments or splints of the required dimensions.

I claim- 8 In a machine for making wood splints, the combination of therevolving cutter-head F, provided with knives having at theircuttingedges a series of molding members separated by interveningcutting-through members, and 9 the bed-plate H, with the feed-rolls N Band drag-rolls N F, all operating together, sub stantially as described,and for the purpose set forth.
